7. Osha (Natalia Tena)
Okay - this one took me ages to get. When Natalia Tena first arrived on our screens in Game of Thrones, her face was instantly recognizable. After several weeks of trying to pick out said face beneath all the Wildling dirt and hair, it finally clicked. Ladies and Gentleman, may I introduce to you, Natalia Tena - aka, Nymphadora Tonks! I'll give you a moment to take that in... Ready? I'll continue... Tonks, an integrated part of the Order of the Phoenix, plays a big part in JK Rowling's epic series but has a somewhat reduced role in the films, as we see her very rarely without the presence of larger, more important members of the Order. Nonetheless, Tena does a superb job in her role. There's very little else that stands out in her relatively short career but you may have seen Tena in About A Boy, Sky Atlantic's Falcon or even briefly in Channel 4 hit, Shameless. Harry Potter aside though, her role as Osha is definitely her biggest to date and I hope that it kick-starts an illustrious career!
